A nurse is teaching a client about using an intrauterine device (IUD) for contraception.Which of the following client statements indicates an understanding of the teaching?

Choice A rationaleIUDs generally require replacement every 3 to 10 years, depending on the type. Replacing the IUD each year is unnecessary and indicates a lack of understanding of appropriate device maintenance.Choice B rationaleIUD use does not require spermicide application. Spermicide is used with barrier methods, whereas IUDs prevent pregnancy through hormonal effects or creating an inhospitable uterine environment.Choice C rationaleMost IUDs do not stop menstrual periods. Hormonal IUDs may reduce bleeding, while copper IUDs can cause heavier periods, so expecting the cessation of periods reflects misinformation.Choice D rationaleChecking for the string monthly ensures proper placement and function of the IUD. This practice helps promptly detect any dislodgment or expulsion, indicating a correct understanding of IUD care.
